Jiangwei School has a total of six classes, each with nearly sixty students, and even retains a sixth grade class.
As far as Wan Feng knew, there were only three brigades in the entire commune that still had sixth-grade classes. The reason was simple: the middle school did not have enough classrooms to accommodate them, so they had to disperse some of the classes to each brigade.
This is a bullshit phenomenon that people thirty years later cannot understand.
But who could have imagined that thirty years later, the once bustling Jiangwei School would merge with Pingshan Brigade School due to a lack of students. Even if a class was merged, it would only have about 30 students. This situation was not unique to Jiangwei, but was common across the country.
The problem of population decline suddenly emerged, seemingly overnight.
But this is not Wan Feng's problem. What he is worried about now is whether Chen Wenxin can embroider the trademark for him and the problem of picking corn.
The requirements for trademarks are not too high. Wanfeng's requirement is that as long as the pattern is 70% or 80% similar, it will be corrected.
It's just a sign.
Chen Wenxin vowed that she would be able to do it well.
Then there is only one problem left for Wan Feng to worry about.
Today is September 1st, and there is still about a month before closing the mountain. Wan Feng calculated that it should be still in time.
In the afternoon, Wan Feng didn't listen to what the teacher said in school. He just wrote and drew on the table.
He wanted to recall and design a corn husking machine.
Even if he remembered, he couldn't build a large one. One reason was the industrial level at that time, and the other was of course the money issue. Zhang Hai would definitely not give him too much money.
It would be better not to bother and get a lightweight one. The price of this model should not exceed one hundred yuan.
Wan Feng was not unfamiliar with this thing. In his previous life, he had played with many agricultural machines, and was familiar with all aspects of it.
Especially after 10 years, every household in the countryside had several electric and oil-fired machines, and almost most people within a radius of 20 miles would ask him to repair any problems with these machines.
The reason is that he repairs well and charges low fees.
Therefore, it would not be difficult for him to make a corn peeling machine as long as the environment allows.
For corn alone, there are husking machines and threshers, as well as integrated husking and threshers.
The integrated peeling and threshing machine is actually not very practical. In some areas, peeling and threshing have to be done separately.
For example, corn, which is naturally very moist, needs to be husked and threshed right after it's been harvested from the field. Where would you find enough space to dry it? Would you dare to store it in a warehouse and bag it if you didn't dry it out?
Another reason is that peeling and threshers are prone to malfunction and difficult to repair.
Therefore, Wan Feng had no intention of combining them together. Skinning and threshing were separate matters.
Anyway, Zhang Hai was only worried about peeling the skin and not worrying about threshing.
The corn husking machine does not have any high technical content. It consists of an electric motor, a frame, a husking mechanism, a thing called a pressurizer and some springs.
Among these components, the electric motor is the most valuable. Although it is only a high-power motor, it will cost at least thirty to forty dollars.
It takes up almost half of Wanfeng’s budget.
The electric motors and frames are easy to deal with. No matter how big the cities in Northeast China are, they have one advantage, that is, almost every city has many factories that can produce many industrial products. The name of the country's first industrial base is not for nothing.
Electric motors, which were considered high-end products at the time, were produced by the Hongya County Electric Motor Factory, and even the Yongshi Commune Machinery Factory produced electric motors of some power.
Since this machine is called a skinning machine, of course the key part is the skinning mechanism.
The main components of the peeling mechanism are two rollers, called the peeling conveying roller and the rubber peeling roller. The peeling conveying roller is provided with shell-breaking teeth.
The peeling roller is a metal roller, while the peeling roller is a metal shaft with a rubber gear sleeve.
The working principle is that when the corn with husk enters the husk peeling part, the shell-breaking teeth on the husk-breaking conveying rod will tear the husk of the corn. Then the corn cob is clamped and moved by the relatively rotating conveying rod and the peeling rod to tear the husk off the corn cob, thereby achieving the purpose of husk peeling. The peeled corn cob is then discharged from the discharge port, and the husk is discharged from another port.
The peeling rate is about 90%, and the grain damage rate is around 1%.
The full metal leather breaking stick can be processed in the factory and can be completed by ordinary lathe workers.
Rubber rollers are not difficult to find. There is a rubber roller factory in Hongya County. You can just pick one that meets the specifications.
In his previous life, there were many kinds of peeling machines and threshers. Wan Feng had fiddled with no less than ten types of peeling machines. His current worry was to recall the one with the most reasonable design, the lowest cost and the most durable one.
After recalling for a class and a half, he finally remembered a peeling machine that weighed only sixty or seventy kilograms. He remembered that it was a machine that could feed two ears of corn at the same time. It was very durable and efficient. It seemed that it was invented by an agricultural college student who was farming at home.
So Wan Feng drew the appearance of the machine on paper according to his memory.
He also wanted to draw its internal structure and component views, but this was a bit difficult for him.
It’s all because he didn’t learn mechanical drawing well in high school. He can draw a view of a simple object, but he is at a loss when it comes to something more complicated.
We have to go to Xiao Dexiang for this, and ask him to make a few wheelchair frames.
After the school bell rang, Wan Feng ran out of the classroom with his schoolbag on his back, ignoring Jiang Jun's calls from behind.
He ran to the carpenter's shop.
Wang He had already finished his wooden box, making three from a single sheet of fiberboard, exactly as Wan Feng had requested. He had even given it a coat of varnish.
Wan Feng checked it carefully and was very satisfied.
"What are you doing? I haven't figured it out for a long time."
It's okay that you don't understand. If you could figure out what it is, it wouldn't be worth much.
"Is this thing sturdy enough for you to make? It won't break if it falls to the ground, right?"
"Tsk, you really want to see my craftsmanship." Wang He picked up a box, took off the back cover and pointed inside: "See, I made the frame inside with such thick wood strips? I tell you, even if the fiberboard on the outside is rotten, the frame inside will not be damaged. Not even a hammer can break it."
A wooden box more than a foot long, the wooden strips inside the frame are actually half an inch wide, and it is indeed possible that it cannot be broken by a hammer.
Wan Feng is a man who always insists on not fooling around with his work. Of course, I can't let you work in vain. Three boxes cost 1.5 yuan. Not only did I give him an extra 50 cents, I also gave him the pack of Guangrong cigarettes that I had only smoked two cigarettes in.
Not only did they use good materials, they also painted it with a bright paint. A pack of 30-cent AU Guangrong cigarettes is nothing.
Not only was Wang He happy, but his father was happy too. It was obvious that after Wan Feng left, the pack of cigarettes would most likely end up in his father's hands.
This is not Wan Feng's business. No matter who has the cigarettes, it will be a waste of money.
